Adapt to terrain with auto-inflating tires for bicycles
If you're navigating rough or changing terrain, tire air pressure becomes a key factor. But on a bicycle, adjustment is manual and you have to stop and get off the bike. Gizmodo found this Adaptrac Adjustable Traction Control System that makes adjustment on the fly possible. It uses a special set of wheel hubs that's connected to a CO2 tank that's mounted on the bike frame. Controls sit on the handlebars with gauges to monitor the pressure.
